what is mgo in manuka honey

MGO in Manuka honey is methylglyoxal , a natural compound that gives Manuka much of its unique antimicrobial “strength” and is used as a potency rating on the jar.

What MGO Actually Is

  • MGO stands for methylglyoxal, an organic compound that occurs naturally in Manuka honey.
  • It forms over time from DHA (dihydroxyacetone), which comes from the nectar of Manuka tree flowers in New Zealand.
  • Manuka honey has far higher MGO levels than regular honey, which is why it’s considered “special.”

In simple terms: MGO is the key marker that makes Manuka honey stand out from normal honey.

What The Numbers Mean (MGO 100+, 250+, 850+…)

  • The number on the label (e.g., MGO 100+, 400+, 850+) is the milligrams of methylglyoxal per kilogram of honey.
  • Higher MGO number = higher concentration of this active compound = stronger activity.
  • Brands use this as a grading system so buyers can compare potency more easily.

Some producers also show a UMF rating alongside MGO; UMF includes MGO plus other markers like leptosperin and DHA to confirm authenticity and overall quality.

Why MGO Matters

  • MGO is closely linked to Manuka honey’s antimicrobial properties, which are part of why it’s used for wellness and sometimes for topical use.
  • It also contributes to the honey’s overall bioactive profile, including antioxidant and anti‑inflammatory effects described in many product guides.
  • Because natural harvests vary, measuring MGO helps sort “milder everyday” honeys from very potent, premium batches.

Quick Forum‑Style Take

If you imagine Manuka honey as a “strength ladder,” MGO is the number printed on each rung:

  • Low–mid MGO: often used as a daily spoonful or in tea.
  • Higher MGO: marketed more for intensive or targeted use and sold at a higher price because of the stronger activity.

Always remember that MGO is a quality marker , not a medical prescription; for any serious condition, it’s best treated as a food supplement, not a replacement for professional care.
